Long term investing means buy and hold. And hold and hold and hold.

A system that does that for you would not really be a trading bot per se, it would just be a general algorithm for "picking stocks". Automating the actual purchasing is probably unnecessary.

If you find one, let us know! Most investors in the world are searching for the such a thing.

And the easiest of such algorithms - ala, just buy a bit of everything - seems to be the winner imho. AKA, indexc investing.

And luckily, this involves roughly zero time and effort. And carries little to no risk of fucking it up enough that you lose everything (see: margin, selling short, day trading, crypto).
